After confirming the change of barges, Li Qinjun imagined the transportation mode of the tug-barge fleet, so he had a main tugboat that was temporarily expedited and renovated by the old shipyard.
At the same time, auxiliary power is even more important in a fleet where a tugboat has to take care of three, five or even more barges. The fleet can decelerate and brake, gather in and out of ports, turn, and even reduce the pressure on the tugboat when crossing rapids. It only needs its own power.
Only by being able to deal with these situations can this form of transportation be used more widely.
The work of cleaning up the mess is not only cleaning up and saving the mess left by the predecessors, but also includes sorting out the previous work, arranging the beginning of the follow-up work, etc.
Li Qinjun did not completely deny Sun Shanming's actions, and even reserved acceptance of most things, such as general-purpose ships and assembly line processing. If he had the ability to make improvements, he organized people to make improvements. If he didn't think he had the ability, he simply
After adaptation and adjustment, it basically remains the same.
For general-purpose ships, Li Qin used the modified barge as a model and designed two types and three models. One type made more improvements to the hull structure layout, mainly widening and making corresponding adjustments and adaptations, increasing installed power, etc.
, a dynamic barge was designed.
According to the design, the performance of the power barge will be more stable, reliable and more powerful than the modified one. It can travel evenly and slowly in ordinary waterways while carrying cargo. Basically, except for the Yangtze River waterway in the Three Gorges area, it can basically sail normally and can be self-propelled.
It can also be towed by a tugboat.
The other model is shortened based on the model. It is basically only about half the size of the powered barge, with a tonnage of more than 200 tons. It is divided into two models with and without auxiliary power. The one with auxiliary power is similar to the model ship.
Horsepower engines have similar effects and are mainly intended to be used to form long tug-barge fleets.
The size and internal layout of the unpowered model are basically the same as the former, but without power, the appearance is more square and coffin-like, and there are devices for hard connection with other hulls on the outside. The hard connection is made of steel, wooden tenons and the like.
The hull is fixed together, while the tow barge only uses cables as soft connections.
These ships can be spliced together to form a huge fleet, which is pushed by tugboats. Because they are spliced, retaining the power system has little practical effect and may even affect their use. The fleet can be used in lake areas where the water flow is relatively gentle.
Large-scale shipping can be carried out under conditions such as waterways and downstream conditions.
This type of barge can be regarded as a regular barge, which is exactly the same as the definition. In addition to forming a fleet, it can also allow a powerful power ship to tow one or two boats against the current and travel on a relatively gentle route. This can
Let the forward and reverse flow basically form a closed loop.
In addition to the barges built at the 300-ton shipyard, the 100-ton repair shop where Li Qinjun works has also designed and built several barge models within 100 tons. Some are towed behind tugboats to load additional coal-fired fuel oil. After all, domestic
There are relatively few power ships, especially in some branch channels at the rear, and there is basically no fixed place to supply these things.
Of course, there are also those used to load cargo, mainly the fifty-ton and one-hundred-ton models. They use steel-framed wooden shells, which are faster to build and lower in cost. As these are put into production one after another, the shipyard is also led by Li Qinjun.
It was transformed into a factory with main manufacturing and auxiliary services.
Regardless of the powered or unpowered barge, the appearance is relatively square. Li Qin adopted Sun Shanming's design considerations and used a straighter hull to speed up the construction speed, reduce the construction cost, difficulty, etc., so the 300-ton shipyard did a lot of ship plate processing
Come out, some parts are common on different ship types.
However, Li Qinjun will still retain the roundness and streamlines where necessary, but will try to use relatively uniform arcs. Usually, the slower the driving speed required in the use scene, the straighter it will be, like a power barge.
It is more rounded than the unpowered barge.
The choice to build barges on a large scale is also due to the actual situation of the Lin family's layout. Although the Lin family is extremely short of transportation capacity in the Three Gorges area, the situation on the downstream Yangtze River waterway is not optimistic either.
The voyage in the Three Gorges area is relatively short. Even including the distance to Sichuan and Chongqing, it is only a few hundred kilometers. However, the distance in the middle and lower reaches is nearly 2,000 kilometers. Once the ships entering Sichuan and Chongqing are solved, the insufficient transportation capacity will appear again.
In the end, after considering the economy, time, etc., we chose to use barges to alleviate the capacity problem on this route.
Use tugboats to tow the barge fleet to the Yichang area, and then either unload and change ships, or use tugboats to directly tow and push a single barge through the rapid waterway of the Three Gorges into Sichuan. When leaving Sichuan, a power barge or a barge loaded with auxiliary power is used.
You can go down the river by yourself, and even sail all the way to the Yangtze River estuary.
Tugboats can push a large fleet of unpowered barges and transport a large amount of cargo down the river at once. When they are pushed back without power, they can find ships with excess power and tow a few cargoes back, thus forming a closed loop.
, allowing the entire transportation system to operate in a circular manner.
However, all this is basically still in the idea or initial stage. Even the old ship has just been modified. After a simple test, Lin Mo was hit by the first long-distance trial transportation.
According to Lin Wenqing, the difficulty of modifying the ship is not too high. It only requires cutting and removing the excess parts, and then performing corresponding welding and modification. Eight ships is a lot, but eight ships were built, among which the corresponding gas cutting and welding were required.
I have already mastered the use of new equipment, so the progress is not slow.
I asked in detail about other aspects of shipbuilding. In fact, the progress of building new ships is not slow, because many talented people have been arranged to help. After the first ship was renovated, the design of the new ship was started. After the ship was refitted, many new ships were built.
The ship has already been put on the slipway and construction has begun.
Because Li Qinjun was only temporarily transferred to organize and clean up the mess, the work of his original factory was not put down. The development during this period was not slow. Although the construction time of barges and other ship types was later, there were also some problems during this period.
There are many other ship types.
Motorboats of several tons or more than ten tons can be used for inspection, measurement and even assisting in clearing waterways. Through channels, the Lin family has obtained a government authorization to clean up waterways, so that they can legitimately carry out waterway cleaning that they want to improve.
Cleanup work.
However, the Lin family has not done much at present. It mainly involves blasting rocks and siltation blockages. The upper reaches of the Yangtze River, such as the Three Gorges and tributary channels, have very fast currents and no one maintains them. Navigation conditions in many places are very poor, and it may happen easily.
The ship was destroyed. In order to avoid causing too much damage, the Lin family had no choice but to do it themselves. Now it is simply a daydream to rely on the national government or local forces.
At this point, Lin Mo gave some suggestions to his family. They could design or even build some special ships for pumping sand, dredging, hoisting stones, etc. to clear the channel in advance. If the Lin family's layout goes smoothly, the transportation volume will become larger and larger in the future.
Just messing around will definitely not solve the problem.
Others include small and medium-sized professional ferries, and medium and short-distance passenger ships, all of which are dozens of tons. The Lin family's future factories will definitely not be crowded in urban areas or even surrounding areas, but they will most likely be located along convenient water transportation areas.
Therefore, it is almost inevitable to provide commuting boats for factory employees to cross the river, return home, etc. There is no way, the domestic foundation is very weak in all aspects, and you have to consider and solve many things by yourself.
In this regard, Lin Mo also gave suggestions. For example, ferries can be changed from simply ferrying people to a type that can quickly get on and off transportation. In this way, it can ferry transportation and even goods across the river, and its application will be wider. Lin Mo even
I also gave a few sketches.
In this era, it is unrealistic to build bridges across rivers. In his vision, factories must not be too close together. However, the Lin family has invested in building factories and is preparing to form an industrial chain with division of labor and cooperation. All kinds of raw materials are inevitable.
Parts and components are transferred between factories. If there is a need to cross a river during the transfer, this type of ship can play a big role.
As for the passenger ship, Lin Mo imitated the passenger ship modified by the Li family and talked about the internal layout and safety measures. Anyway, it is a ship for medium and short distances. It only has seats and beds. There is no need for fancy cabins.
, for workers, speed and convenience are real.
After asking about the situation at the shipyard in detail and giving some suggestions, Lin Mo learned about other industries that the Lin family is involved in. In fact, there is not much to say. There is a mixed profit and loss, some make a lot of money, and some lose money to grandma's family.
Some are half-dead, breaking even, or barely making a profit. There are all kinds of situations. It’s no wonder that many outsiders regard these as jokes.
The best-run companies are undoubtedly the factories that produce various types of rubber products. But as Lin Mo guessed, there are many more competitors. However, the Lin family has also developed many production lines or factories for new products. Although the profit margin has dropped.
, but the profits are still huge.
The main reason is that the current price of rubber is too low. I originally wanted to raise the price, but the price just increased. The rubber forests that had been abandoned or even abandoned were immediately picked up again, and the vacancies were quickly filled, pushing the price down again.
Going back, the overall price has not increased much.
The demand for rubber soared during World War I, and the rubber boom caused by soaring rubber prices led to the planting of a large number of rubber trees in Southeast Asia. After the war, the rapid development of industries with huge demand for rubber such as automobiles led to the continued development of the rubber planting industry.
, the planting volume is increasing year by year.
However, after the Great Recession in the United States, the global economy was half-dead. The demand for rubber plummeted, and the price of rubber fell directly below the floor price. Many plantations had to pay extra for harvesting, so they simply abandoned the harvest or even abandoned it.
.
Rubber trees are perennial crops. They are distinguished by their growth years, plant growth, and other factors. In addition, the yield and quality of rubber trees in different regions are different, as well as the cost of labor and transportation. Many plantations that follow the trend cannot compare with others in terms of costs.
, the cost is greater than the selling price, then we can only abandon the harvest, abandon it or even cut it down to reduce losses.
However, most of the trees that have reached the gum-producing age will not be cut down. They can continue to survive and grow without cutting or even abandoning them. What if the price suddenly rises? Right? In fact, the sunk cost is too high, and few people can accept the reality.
Cut off the meat and leave the market, so these potential production capacities have been waiting and watching, and the gap will be closed as soon as the price rises.
Of course, Lin Mo's previous thoughts seriously underestimated the supply capacity of the rubber industry and overestimated the capabilities of the Lin family, or in other words, overestimated the consumption power of the domestic market at this stage.
Although the Lin family has developed and produced many rubber products that are popular in the country, the demand is estimated to be far less than the potential output of rubber. He now estimates that if he wants to significantly increase the price of rubber, another war may have to break out.
